Fibres make up 90% of the A-Fibres, while the rest are A-Beta Fibres.
** Have a relatively low-threshold sensory apparatus.
** Mainly located at the pulp-dentine border at the top of the pulp, and more specifically concentrated in the pulp horn.
** Have a relatively small diameter with a relatively slow conduction velocity. They are is still faster than C-Fibres.
** A-Fibres transmit signals to the brainstem and then to the contralateral thalamus.
** Able to respond to stimuli through a shell of calcified tissue due to
